Wio LTE Tracker: SD Card examples do not compile

Post by matthias.gruenewald » Mon Nov 11, 2019 2:57 pm

Hello together,

when I try to compile any of the incldued SD card examples (e.g., Datalogger), I get the errors below. It seems that are two implementation of the SPI interface included which do not work together. Any idea how to fix this?

Hi matthias.gruenewald,

Which library are you using? I tried to replicate the error by compiling the DataLogger example code and I didn't got any error . can you please update to the latest Arduino IDE and Library

Library link: https://github.com/Seeed-Studio/Wio_LTE_Arduino_Library
Thank You :) .
